The wireless system of communication has recently known a considerable evolution, which has led to the appearance of a new type of networks called Vehicular Ad hoc Networks (VANET). This innovative approach is crucial for enhancing the quality of the driving experience as a whole: the safety of the drivers, traffic management and the entertainment of the passengers. Thus, the selection of an appropriate routing protocol is necessary to support high mobility, rapid changing topology and capacity of mobility prediction. In this paper, we evaluate the performance of a set of well-known routing protocols used in VANET, namely AODV, DSR and DSDV in terms of Packet Delivery Ratio (PDR), Throughput, and Normalized Routing Load (NRL), in order to find out the suitable routing protocol for high density traffic area such as Casablanca. In this paper, the real map of Casablanca is edited by Open Street Map …
